In this case, the auditory system undergoes temporary changes caused by a decrease in the oxygen tension of the cochlear endolymph that leads to vasoconstriction of the local vessels.
12.
For example, certain cells respond to changes in oxygen tension as part of their normal development, such as chondrocytes, which must adapt to low oxygen conditions or hypoxia during skeletal development.
13.
The protein encoded by this gene is the alpha-3 subunit of one of several alpha / beta-subunit heterodimeric transcription factors that regulate many adaptive responses to low oxygen tension ( hypoxia ).
14.
As such, fetal hemoglobin must be able to bind oxygen with greater affinity than adult hemoglobin in order to compensate for the relatively lower oxygen tension of the maternal blood supplying the chorion.
15.
The converse happens when the carbon dioxide tension falls, or, again to a lesser extent, the oxygen tension rises : the rate and depth of breathing are reduced till blood gas normality is restored.
16.
The normal oxygen tension in the foot is approximately 60 mmHg and a normal chest / foot ratio is approximately 0.9 . Many factors can limit the accuracy of the test including edema, temperature, inflammation, medications, and stress.
17.
In people acclimated to high altitudes, the concentration of 2, 3-Bisphosphoglycerate ( 2, 3-BPG ) in the blood is increased, which allows these individuals to deliver a larger amount of oxygen to tissues under conditions of lower oxygen tension.
18.
This means that the oxygen binding curve for fetal hemoglobin is left-shifted ( i . e ., a higher percentage of hemoglobin has oxygen bound to it at lower oxygen tension ), in comparison to that of adult hemoglobin.
19.
Sickle cell disease is a blood disorder in which there is a single amino acid substitution in the hemoglobin protein of the red blood cells, which causes these cells to assume a sickle shape, especially when under low oxygen tension.
20.
While in internship, Stone published one of the first case reports on the formation of a liver cancer in patients who had hepatitis C . His subsequent residency research returned to the area of tissue oxygenation, focusing on ligament oxygen tension using a self-designed oximeter.
